Powerful and efficient environmental protection
Equipped with Cummins QSL9 high-power engine, the power output is abundant, meeting the needs of heavy-duty construction; Compliant with Tier 3 emission standards, balancing environmental protection and energy consumption, suitable for various construction site operation requirements.
Structural strengthening, full stability
The four-bar linkage structure is widened and raised, and the mast is equipped with guide rails and three sided pressure plates to enhance the anti overturning ability during drilling; The lightweight design of the overhead crane reduces the top load, and with the overall counterweight, the stability of the entire machine operation is significantly improved.
Hydraulic system is efficient and reliable
Adopting Kawasaki rotary drilling dedicated main control valve and large diameter and large flow main and auxiliary pumps, the hydraulic system has fast response speed and stable pressure. With a high flow configuration of 289 × 2+86L/min, it is suitable for precise drilling under complex geological conditions and reduces the risk of drilling jamming.
Outstanding hoisting and drilling capabilities
The main hoist has a lifting force of 270kN and a maximum lifting speed of 60m/min. With a pressure of 250kN and an extended stroke of 5680mm, it can efficiently complete deep hole and large-diameter drilling operations, with excellent rock penetration ability and drilling efficiency.
